I am sorry, but the police bring this on themselves. There was no need to kick the door in. They did it to get their jollies off. In WI they have also done it at the behest of the prosecutor for political intimidation.
I think the procedure to get a search warrant needs to also address the methods used. Maybe judges can bring some sanity to this madness.
No-knocks are designed to assure that there is no municipal money used for a trial.
